三维X射线显微断层扫描已被用来跟踪转移过程中的铝粉的运动，所带来的降低到一个圆柱形模具包含一个未压实的铝/锡粉末混合物的冲头。在跟踪锡标记颗粒时，图像相关性使得能够确定冲头周围的粉末转移机制。该方法/技术适用于金属和陶瓷粉末的粉末加工研究。(c)2005年由Elsevier Ltd.代表Acta Materialia Inc.出版。
Three-dimensional X-ray microtomography has been employed to trace the movement of aluminium powder during transfer, brought about by the lowering of a punch into a cylindrical die containing an uncompacted aluminium/tin powder blend. In tracking the tin marker particles, image correlation enabled the determination of powder transfer mechanisms around the punch. The method/technique is applicable to the study of the powder processing of metal and ceramic powders. (c) 2005 Published by Elsevier Ltd. on behalf of Acta Materialia Inc.
